Rated 5 out of 5Â by BenLe Definately worth every penny
Coming from a TI calculator, it definitely took some some getting used to it, but the application and function layouts are very efficient once I got familiar with them. Having such a high resolution display (well, high for calculators, that is) makes graphs and charts appear very detailed, and depending on font size and complexity of entry, it's nice to be able to see the last 10 or so entries at once. The ability to switch from app to app in only a few keypresses (or taps) is extremely useful. The separation of the Home and CAS menus as well as the separate apps is convenient, and both talk nicely to their counterparts (get from Home/CAS, importing data to inference, et cetera). Finally, the programming language is fast, function library is extensive, and the design is ultra sleek.

Rated 5 out of 5Â by 1JoeP1 Confusing Research/Poor Results
First of all, the Prime appears to be a high quality calculator, but for the following reasons it does not meet my expectations. I researched this product, the Prime, several times to make sure I could write programs, similar to my HP 42S; which I referenced in my written dialog with your agents. While they were friendly, I could not get a yes or no answer, but was assured that it would out perform the 42S. So far, I can't find a way to introduce programs to the Prime. I beginning to think it is worthless for my purpose. I would like to return it, but I don't have the original package material. I have two HP calculators (simulation models) on my old PC, but now that I have upgraded to a new PC with Windows 8.1, they are not compatible. I have gotten myself into a bad deal and I have no use for the Prime. Do you have any suggestions? I have one HP 42S in my possession and when that is gone I am out of luck.

Rated 4 out of 5Â by nancerp Impressive, but could use some polish
First, some background: I am an engineer by profession, a lifelong calculator buff, and an HP user since the late 1980s. I've had a 28S and a 48SX. Most of my heavy-duty analysis is done on the computer (primarily in FORTRAN), but I occasionally want/need to perform some smaller-scale calculations without going to a keyboard. The Prime wasn't a necessity for me, but I had some gift cards to spend, so I was able to pick it up for very little out of pocket.
What follows are my opinions on the device thus far, after having it for about a month.
Pros:
Physically, the calculator is fantastic. It looks great; it is light yet feels sturdy; the screen is great, and touch works well; and the keys feel a lot like the keys on my 28S.
The calculator is very responsive, and has lots of built-in functionality. Many operations that had to be programmed into my 48SX are native on the Prime, along with many more.
PC connectivity is a big advantage. I really like being able to write code on the PC (rather than keying it into the calculator directly), testing it on the emulator, and sending it to the device when I'm done. The high-level language structure also means I can copy/paste bits of FORTRAN code and reformat them only slightly to work on the Prime.
Cons:
Usage is definitely non-intuitive after working with RPN/RPL on the 28S and 48SX for many years. I'm not a big fan of the pre-defined variables (and pre-associated variable types) implemented on the Prime, and switching between textbook/algebraic/RPN/CAS is a little strange. As some other Prime users have pointed out, some things require a lot more keystrokes than they used to.
Connectivity with the PC feels a bit half-baked. Sometimes (but not always) my Prime will not charge when connected via USB; sometimes (but not always) I cannot send programs directly from the emulator to the device. It took many attempts on three different PCs, and assistance from HP support, to update the firmware on the calculator.
RPN on the Prime also seems like an unfinished work. The 28S and 48SX were both "RPN native", and algebraic mode sat on top of RPN. With the Prime, RPN, textbook/algebraic, and CAS are quite separate, and some things do not work as well in RPN as in the other modes. For example, if I wish to store 78 in the variable A7, I have to create the variable A7 first, then do 78 'A7' Sto>. Otherwise I get a syntax error.
It is unfortunate that the equation library, periodic table, and 3D graphing are not built-in. I am sure the color touchscreen would make the latter two capabilities, in particular, fairly spectacular.
Also unfortunate is that no print manual (not just a Quick Start guide) is included with the calculator. The User Guide is fairly informative, but not as comprehensive as it could be. When I got my 28S and 48SX, each had extensive print documentation that, in my opinion, also served well as a tutorial. After spending a couple of days with those manuals, I felt like I knew enough to do most of what I needed to do.
Other notes:
The Internet has already been a useful resource for learning how to use the calculator better, and for downloading some impressive programs written by others, including a 3D graphing capability. These resources are in fact more useful than the User Guide.
Quite a few people on various Internet forums have reported serious stability issues, such as several reboots a day. So far, I have experienced no such reboots during regular use; I did freeze the calculator several times while attempting to update the firmware.
I assume (hope?) that future firmware updates will add features to the calculator and improve its robustness.
Nits:
The sliding case is OK, but a little hard to get on/off. I would definitely buy an HP leather case if one were available for the Prime. (Does the HP 50g case fit it?)
I like the option for a dark screen (white text on black background), but it would also be nice to change the font color. Bright blue on black, or green on black, would be great.
Summary:
While I think there are some kinks to work out, I am quite pleased with the calculator in its present state. (More so after the firmware update.) I've effectively transitioned away from my 48SX in favor of the Prime. The combination of build quality, color touchscreen, functionality, and (admittedly immature) RPN make the calculator a great value for the money.
I really do hope that HP plans to offer additional updates in the future, both to correct issues and to add new features.

Rated 4 out of 5Â by greystoke This product perfroms!
While the performance meets my needs, I need a magnifying glass to read the tiny blue shifted functions. This could have been better human engineered. I am disappointed with this. HP should provide a keyboard overlay to make the shifted functions more user friendly.

Rated 5 out of 5Â by Juergen This calculator is fabulous.
The implementation of functions, use of apps and overall computing power is impressive. The speed of getting graphs is phenomenal. I simply love this product and highly recommend it.
The instruction manual comes on a disk and is thorough. I have been reading and trying the examples and everything works well. It seems to me that this is definitely the best calculator yet.
There is one complaint I have, and that is the keyboard. The colors are not very definitive, and reading the sub-functions is very difficult. I have an HP-48 GX and there is no comparison as far as the keyboard is concerned, but...as I have read an article from an HP engineer, the cost to produce a calculator like the HP 48 GX would be prohibitive, and not competitive. So, I have no problem to adapt, same goes for the RPN functionality, it's best to go with the flow and accept the default. One can still use the RPN functions, but it is limited and not allowed in the CAS. One other issue is the manuals now-a-days, they are on a CD, I would gladly pay the price for a printed manual if it were offered as an option. Overall, I am extremely pleased with this product, and it is just a joy to use it.
